To ctZZ whom/,it may concern:

Be it known that we, ARTHUR `ANNnsLEY 'VOYsEY, a resident of Mid Higham, by Rochester, andHARoLD HEnoN HosAcK, a resident of Shorne, by Gravesend, England, subjects of theQueen of Great Britain and Ireland, have invented certain new and useful Apparatus for Breaking Up Roads and other Surfaces, (for which we have obtainedILetters Patent in France, No. 220,063, dated March 11, 1892, and in Belgium, No. 98,779, dated March 12, 1892;) and we do hereby declare that the following is a full, clear, and exact description of the invention, which will 1enable others skilled in the art to which it appertains to make and use the same.

This invention has reference to apparatus for breaking up Macadam roads and analogous surfaces, but particularly Macadam roads; and consists of certain constructions and modes of operating machinery of the kind hereinafter fully specified with reference to the drawings, the novel features concerning which are more particularly specified in the claiming lauses concluding this specification.

Aside elevation,and Fig. 2 is a plan showing a mechanism according to our invention.

With reference to the drawings,the arrangement 'therein shown consists, principally, of a motor (namely, a road roller or traction engine,)a frameor carriage connected.'- rthereto, and tool holder, the tools oeing mountedY in shafts yor spindles and adapted to be revolved.

A designates, generally, the motor, say an ordinary road steam roller ortraction engine, of which c is the tender Ior, rear tank, a. are the vhinder road wheels, and a2 is the fly wheel.

b are brackets fitting on the sides of the Nprzzons. man

` tank or tender a, and secured thereto` by bolts 5o and nuts b', said bolts passing through slotted apertures b2 in b, whereby longitudinal adjustment of the brackets (and,'as hereinafter described, the drive chain) is obtained. The ends of these brackets form bearings.

X generally designates Athe part of the machinery on which'the breaking tools are provided and carried. This machinery comprises side frames c connected to the bracktsb by the shaft d, which revolves in the bearings thereof; vsupporting-and ,running wheels'e mounted on the outside of c; cross rods f connecting the two side frames c together; bars g fixed to the frames c for regulating and supporting the tool holder; a movable tool holder frame, adjustable laterally, and consisting of side plates h, connecting rods h', andbear-v ings Won the plates h; tools 7c mounted in a general tool carrier or holder fi; a shaft Z connecting the upper corners of the tool carrier frameplates h together; a supporting piece fm, sliding on Z, and having an upper screwed vertical part m fitted and adapted to rotate therein,'and having actuating handles m2 fixed thereon; la nut fnJ (through which m screws) supported and adapt-ed to slide longitudinally in the bars g; and a set nut 'n' withhandle to tighten and lock the screwed rod fmin the nut n. Y The tools k are upright or inclined and are rotated axially, (that is, each` tool is rotated) and they are fixed in tool holding shafts It', which are supported by, and revolve in, the general holder ft', and their upper endsare each provided with a s'pur wheel k2 meshing with its neighbor, the first shaft 7o being driven `from the shaft j by the bevel wheels k3, while the shaft j itself is-driven from the motor A. through a sprocketwheel Z (which may be on the crank shaft ef the engine) a pitch'chain 2, driven by 1; a sprocket wheel 3,'ix`e`d on`v the shaft cl and driven by 2; a sprocket wheel,4,`also fixed on d, anddriving the pitchchain 5; a sprocket wheel 6 fixed on the shaft?, mounted and adapted to rotate in the side frames c, and driven by the chain'; sprocket wh'eelB mounted loosely and adapted to slide on the square shaft 7, and driven thereby; and a pitch chain l0 driven by 8, and driving the sprocket wheel ll, which is fixed upon the tool driving shaft j. Thus, in action, when the engine of the roller or traction engine is set in motion and propels the roller, it also rotates the tools 7c.

The breaking of the road or other surface may be eected when the engine is going either forward or backward, This is a considerable advantage.

By adjusting the bearing plates b ou the tank a, any desired tension on the pitch chain 2 can be obtained.

The front part of the frame c, as will be seen, are 'connected to, and the whole mechanism X is propelled by, the roller A from the shaft d, while the rear part of the said frame is supported by the wheels e; and the frames c with the cross rods f and bars g constitute a carriage or truck. The wheels e are mounted practically in the same vertical plane as the axis of the tool holder t, or nearly so; by arranging these wheels and tools in this relation to each other, the depth to which the tools 7o enter into the surface of the road, will be the same at all times and in allconditions of its surface, since the contour of the surface of the road is followed by the wheels e. As already stated, this mechanism provides for the tool 4holder and tools being adj usted transversely or laterally. This is done by shifting the tool holder carrier along its supporting rods f and moving the nut n along the grooved inside edges of the bars g, the said nut having rounded sides which slide in the plates. This transverse or lateral adjustment of the tools enables the edges or sides of the road or other surface to be broken.

To lift up the tool carrier, or to lower it onto the ground, the rod m is rotated by the handles m2; and it, the rod m', being mounted at its lower end in the piece or block m, it passes upward or downward through the nut n and so moves the tool carrier up or down. The

' tool holder plates or frames h, when being lifted or lowered move or rock about their supporting rods f, the parts of said plates at which the rods f pass through them being slotted out as shown by the dotted line at h3 to allow of the required amount of movement. It is preferred that in going ahead, the tools should be inclined in the direction of the line marked Ahead while for going astern they should assume the angle of the line marked Astern. These positions are lixed by moving the tool holderz' about on the shaft jot the tool holder to the required degree, and then inserting a holding pin through one of the holes 7a4 in the side frame h, and through a corresponding hole 705 in the flanges 7c and 72 of the tool holder and shaft j. In addition to this a key may be driven in into key-ways k7 in the end of the shaft j. This shaft j in this case is in two end parts, each being provided with a flange y2 which is bolted to the flanges k6 of the tool holder.

suitable kind may be used. When of screw form they should be arranged to act alternately right and left hand to neutralize side thrust.

In cases where the weight of the road roller or traction engine is not employed to keep the tools in the road surface, the weight of the mechanism is caused to keep the tools in the road surface and is made sufficiently heavy to prevent the tools jumping out of the road, say when they come on particularly hard bits of road. By our invention, to avoid having to raise such a weight oil' the surface when it is desired to raise the tools out of the ground, the tool carrier is mounted on the main frame or carriage, (which is the heaviest part of the machinery) and is raised thereon without having to lift the whole weight, but at the same time when the tools are lowered, the whole weight of the main carriage or frame, which is supported on its running wheels, comes on the tools to keep them in.
